.SPRAY NOZZLE,

Application led Februaryv 16, 19,24. i Serial No. 693,218.,

Be itknown that I, CAssiUs M. CLAY B Amn, a' citizen of the UnitedStates .of America, and a resident of Chicago, county Aof Cook, andState of Illinois, have invented la new and useful Improvement 1n SprayNozzles, of which .the following is a specification.

This invention relates' to garden hosev provided with .spray nozzlessecured thereto at intervals along its length so that the ordi` naryflexible garden hose may be employed for sprinkling a relatively largearea.

' The present application for patent is a.

continuation in part of the previously led application No. 516,726,filed November 21,

The object of the invention is to provide a Vspray nozzle having athreaded conical nip-r ple with a small sharpened'point at the endy ofthe nipple so that the nozzle may be forced into the side of'a rubberhose .of

standard construction without injury to the line 2 2 of Fig. 1.v

fabric. It is also a purpose of the invention to provide a constructionwhich will insure a permanently .water-tight connection and v preventaccess of moistureto the fabric of the hose. v

The objects of the invention are accomplished by the constructionillustratedin the drawing, in which :-7

Figure 1 is a plan view of a fragment of garden hose equipped with oneof the spray` nozzles. v l.

Fig. 2 is a sectional viewV takenv alor/1g the Fig. 3 isa side view ofthe spra nozzle. Fig. 4 is another side view of t e spray nozzle takenat'. right angles to the view shown in Fig. 3.

/5 shows a slightly modified construc-V i tion in which the sharpenedend of the threaded nipple is not beveled off at one side as shown inthe remaining figures.

The improved spraying device may be ap plied to a garden hose by hand orwith the use of pliers simply by forcing and 'screwing the sharpenedthreaded nippleof the deylill vice through the wall .of the hose.Without preliminary puncturing of the hose, the shape of nipple permitsit to be screwed through rubber and fabric so as to spread fabricwithout injuring same. The'fabric used in garden hose is frequently ofvery open mesh, and, therefore, the spray device when applied to thehose, merely spreads the meshes of the fabric without cutting it. The`conical nipple also wedges the rubber body part ofthe,hose`outwardly,`and the rubber hning resiliently engages the nipple,preventing 'water from traveling upwardly f' along the exterior of thenipple tothe fab` ric.. The fabric should be kept dry since when wateris permitted to travel along the fabric, the hose deteriorates fasterthan ordinarily.l l

The drawing shows a flexible garden hose '1 formed as usual of a seriesof rubbertubes 2, separated by the fabric tubes 3. The spray nozzleincludes a head 4 slotted at 5 for, receiving a screw driver, if'desired, and having a concave recess 6 in its side above the circularflange 7. l' The tapered threaded nipple or shank'8 is provided with anaxial perforation 9 for conducting and projecting lwater from the hoseagainst the concave sur-A face of the recess v6, -this surface servingto "spread thev jet of water. The end 10 of the conical nipple issharpened, and to further bring it to a point, the end of the nipple maybe beveled off as at 11. 'l a yIn applying the spray nozzles to thegarden hose, it is merely necessary to screw them down tightly yintoposition, the tapered nipple serving to spread the fabric and the rubberof the hose without much injury thereto. l

The nozzle nipples may be dipped in lrubber cement'before applying thenozzles to the hose, but this is not essential for a watertightconnection, since the ,conicall nipples .merely l s read the rubberoutwardly and downwar ly, resulting in the rubber becoming compressedaround the nipples.

Iclaim: .Y .v 1. A spray nozzle ofthe class described comprising4 a bodyhaving a head and a conif cal'threaded hollow nipple sharpened at its en2. The combination with a arden hose of a spray nozzle comprising a odyhaving'a head, and a conical threaded hollow nipple sharpened at its endand extending through the side of the hose.

3. A spray nozzle ofthe class described I' cal threaded hollow nipplesharpened at its l i comprising a body having a head and a coniend, saidhead having a spreading and deflecting surface in position to be engagedby fluid passingthrough said nipple.

4. -A spray nozzle of the class described comprising a bod having a headand a conical threaded holfbw nipple,- said head having a spreudingunddeecting surface in position to be engaged by fiuid passing through saidnippie, and the end of Suid nipplcbeing beveled 0E at one side to bringit to :L point.

5. The combination with a garden hoseof a spray nozzle, comprising ahead and a threaded hollow nipple sharpened at its end wherebyvthenipple may be screwedthrough the rubber und fabric of the hose so asto spread the fabric without injuring the saine. 10
